To all whom it may concern:

Be it known that we, THoMAs J. BRQNSON and, ALEXANDER ARMSTRONG, of Jacksonville, in the county ofMorgan and Stateof Illinois, have invented certain new and useful Improvements in Railway Sleepers and Chairs;

and we do hereby declare that thefollowing is a fee full, clear, and exact description of the inveniion, such as will enable others skilled in the art to which it appertains to make anduse the same,reference being bad to the accompanying drawings, which form a part of this specification, and in which ers and chairs; and it consists in the improved construction andcombination of parts of the same, asthereiuafter more fully described and claimed.

In the accompanying drawings, theletterA.

represents the rails, which are of the usual construction, and B the sleepers. The sleep ers are of metal, and have flat ends 0, which have on their upper surface shoulders D, having flanges or lips E, which clasp "the inner bottom flange ot' the rails.

Outside the rails are clamps F, having similar flanges, G, and

which are fastened to the flat ends of the sleepers by means of one ormore screw-bolts, H,

the lower square; heads, I, of which fit into i square recesses J in the chairs K, while they are fastened upon the. upper surface of the clamps by nuts L. The rails are held. fast by shown in the drawings. is shown having two recesses, M and N, crossing each other at right angles, clamping the end of the sleeper and the rail, the recess J, for the the clamps D and F, and the sleepers are prevented from sliding sidewise by thesquare bolt-heads fitting in to the recessesin the chairs. The chairs may be made'of metal, wood, stone,

or any other suitable material, and are laid firmly down inthe ballast. Three slightvariations in the construction of these chairs are In Fig. 2 the chair reception of the square bolt-head, being in the bottom of recessN- In Fig. 3 the chairis showin having only recess N for the reception of the flat end of the sleeper, and recess J in the hot 7 tom of recess N, while in Fig. 4 only the recesses J hold the sleeper, which .in that case is supported by the ballast only besides the square bolt-heads.

Having thus described our invention, we

claim and desire to secure by Letters Patent of the United States- The herein-described railway sleeper and chair, consisting of the sleepers B, having flat i ends 0 and flanged shoulders D, flanged clamps 1},SGI'GW-b0lt8 H, having square heads I and nuts L, and recessed chairs K, haying square recesses J for the reception of the square bolt-heads I, all constructed and combined substantiallyias'and for the purpose shown and set forth.
